Cryogenic technology is used in a variety of industries, including the aerospace, chemical, food manufacturing and pharmaceutical industries. If your business falls into one of these industries and you use cryogenic technology, there is a good chance that you will need to replace the cryogenic valves periodically.
When you are trying to find a valve for your equipment, you have to determine if you need a valve that accommodates liquid carbon dioxide or liquid nitrogen. While there are some universal valves available, these aren't usually as efficient as a specialty valve that is made for the liquid gas you use.
Another consideration is the industry in which your company operates. Cryogenic valves that are used in the aerospace industry are usually slightly different than those used in the food manufacturing industry. In some cases, this difference is only in the acceptable cleaning method for the piece, even though the pieces look alike.
The last consideration you need to be aware of is the cryogenic valve test result score. This score rates the temperatures at which the valve will operate. This rating must be compatible with the rating on your equipment's shut-off valve. Reputable companies, such as Cryofab, Valcor and Assure Automation will provide these ratings upon request.
